slog: use middle dot for TextHandler groups/scopes

Use a Unicode middle dot '·' as the separator between group/scope names
and keys in the TextHandler, instead of an ordinary dot '.'.

Although both dot and middle-dot may appear in a user-supplied
attribute key, making unambiguous parsing into groups impossible,
middle-dot is expected to be much less common, thus reducing the
frequency of ambiguity. If a user wants to escape, they can use
ReplaceAttr.

Alternative encodings that unambiguously preserve the group/key
separation would make parsing more complicated than simply calling
strconv.Unquote.
